“The ruling said that GC beliefs are WORIADS but how they are expressed must not infringe on the rights or dignity of others. So, again, lots of room for different interpretation.”
It was the Forstater Appeal Tribunal which established the position you set out.
My recollection of the Edinburgh Rape Crisis Centre employment tribunal re constructive dismissal etc was that - taking account of the legal position established in Forstater - NC’s focus was on whether there was any way the claimant could have asked for advice on what to say to the service user about whether the ERCC worker supporting her would be female without the request for advice resulting in the claimant being subjected to a disciplinary for asking the question.
NC is going down a similar route here - establishing that there was no hope of the claimant raising concerns about single sex spaces without being subject to a complaint from Upton.
